They do because they can. To think otherwise is naive. The Chinese government ordered 38,000 students from public schools in the area to work at Foxcom when they couldn't recruit enough workers. The students couldn't refuse. That alone should tell you how far they will go to achieve their goals.

yes, they should hire from Walmart, target...
File a lawsuit if you are fired without a good reason. Don't just complain without any action. Isn't that what losers do?
wait, is that your imagination or reality, you look like full of imagination. we have to be careful of what you said...

let me quote a comment posted long time ago
"with the military power much larger than all the other countries in the world combined, a country deep in debt like Greece if not worse, a country with 50million people on food stamp, with huge cut on public education/services... but still spend 25% of its budget on military (in the mean while, with no plan on how to pay off its debt)"
who is the threat to world peace?
Back to the original topic, in a thief's eye, everyone has the intention to be a thief

QUOTE: Interesting. Guilty until prove innocent. The principle used here is opposite to the court cases
That would be Napoleonic code ... the same principle that applies in North America (NA) when you get a parking/driving ticket. The opposite of the innocent until proven guilty scenario that applies in NA criminal courts.

Huawei's problems have been going on for nearly 10 years.

There can be other motivations, but from engineering viewpoints, many are fairly clear to see.

Huawei and ZTE got to where they are by hiring exLucent and Nortel employees. The non-Chinese were fired after a couple of years after their brain dump, the Chinese (Communist party members who came over as 'students' and infiltrated american companies), are retained to help the main land Chinese master the technology. Soon they will be reintroduced to other American companies where the Chinese lack technology. Long time moles are entering defense companies now. This is Chinese military intelligence strategy.

Poor logic -- Your lack of imagination, doesn't mean it doesn't exist.
The Chinese have a military objective and the commercial side is just a facade. All of China's neighbors know how expansionist she is. Be very careful. The Chinese have 100 year plans. Incremental advances in her military industrial complex will compound into a formidable enemy one day. Next to N.Korea, Iran and few other banana republics, she is the biggest repressor of freedom and democracy in the world.
I'm praying for the Chinese people to live free and peacefully one day with the rest of humanity.
